We are inextricably linked with our compatriots. The supply of high-quality blood in herman melville is a very important part of modern medical care. Blood cannot be synthesized, so it must be collected from volunteers. However, many people are afraid of donating blood for many reasons, from fear of pain to fear of getting sick. In fact, blood donation is very safe, and there are already many preventive measures. There is no reason to worry about infectious diseases. The most serious risk of blood donation should be "adverse reaction", which usually has two forms, namely dizziness or cyanosis. If you follow the following instructions, you can reduce these two kinds of adverse reactions.
Methods 1: Before blood donation
1. Drink more water or juice the night before blood donation and in the morning. The primary cause of dizziness and fatigue is the drop of blood pressure. Replenishing your body with enough water or juice helps to maintain blood pressure. The Australian Red Cross recommends drinking more water, especially warm water, 24 hours before blood donation, and drinking four glasses of water or juice 3 hours before blood donation. If you donate plasma or platelets, drink at least 6-8 glasses of water.
Don't drink coffee, because it will promote the body to excrete water.
2. Eat something 3 hours before blood donation. It is not recommended to donate blood on an empty stomach; Eating can keep blood pressure stable and you will feel better after donating blood. Food in the blood can prevent dizziness. If you like breakfast, you can eat something light, such as porridge and toast, or have a light lunch, such as sandwiches and some fruits.
If you think you might get sick during blood donation, don't eat before blood donation.
Don't eat greasy food within 24 hours before donating blood. Too much oil in your blood may prevent your donated blood from passing some necessary blood tests. If they can't complete all the tests, they may have to discard your blood. You don't want to let your efforts go to waste!
Two weeks before the appointed time, you can eat some iron-containing foods, such as spinach, whole wheat, eggs, beef and so on. High levels of vitamin C can help iron absorption (eat citrus fruits and juices, or take vitamin C tablets as recommended by doctors). Test your blood iron content before donating blood to see if you are suitable-you should let the recipient receive qualified blood.
3. Prepare your ID card and blood donation card in advance, and put them with the things you want to bring. Prevent tension and fall on the day. Blood donation card can speed up the process, because your blood donation card number allows them to quickly find your specific information. Answer all employees' questions or questions honestly. Some activities will increase the probability of blood-borne diseases, and people who participate in these activities may not donate blood for a period of time. Some questions related to sex life may be awkward, but people who work in blood donation centers are very professional. They have seen many things.
Your blood donation may be delayed, but others will not know the reason unless you tell others yourself. If you need a less embarrassing reason to tell your friends or colleagues, low iron is the most common reason to postpone blood donation. Low blood pressure, high blood pressure and high body temperature are all good excuses that are not easy to cause embarrassment. If you feel the need to prepare some excuses, you can ask the applicants privately.
Method 2: When donating blood
1. At this time, you will have a small monitoring to monitor your temperature, pulse and blood pressure.
2. Wait for the nurse to measure your hemoglobin. Will stick a needle in your fingertips, and the result requires you to donate blood within the normal range to ensure that blood donation will not make you sick and anemia.
If your hands or feet feel cold, you can ask for a blanket. This is a sign that your blood pressure is beginning to drop. A warm blanket will relax you.
4. When the needle goes in, take a deep breath or pinch yourself to distract yourself. Don't hold your breath. If you do this, you may be out of breath. Don't worry-many people say it's not very painful, but it looks like a mosquito bite. It will be a little uncomfortable. The less nervous you are, the better. Naturally know your limitations-if you are too nervous, tell the blood collector in advance.
5. Relax. Nervousness can also lower your blood pressure and lead to dizziness. Talking to the person who drew your blood will make you feel better and let him/her explain what he/she has done to you. Find ways to distract you-chew gum, sing, recite something, think about the ending of a book you read or a TV series you are chasing, listen to songs in MP3 or CD players, think about the value of your blood donation, and even talk to people who collect your blood about life-changing stories they know.
